This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ40X200-30, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAU replacement uses the same profile body, bore, stroke, force and SC-series mounting. It moves to the current CMSG / DMSG / EMSG sensor switches (the SU used CS1-B / DS1-B) and adds the SAUF valve-integrated option.
Airtac SUJ Adjustable Cylinder SUJ40X200-30
The AirTAC Airtac SUJ Adjustable Cylinder SUJ40X200-30 is a double-acting profile-type standard cylinder with a Ø40mm bore and 200mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ40X200-30, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ40X200-30
The AirTAC SUJ40X200-30 is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 170-200 mm stroke out of the 200 mm nominal maximum.
This SUJ series is discontinued and the direct replacement is the SAUJ40X200-30, matching the bore, stroke, force, port, and FA/LB mounting. The SAUJ upgrade uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches used here. Note this non-magnet SKU cannot take a switch, and the stop screw sets end position but is not a load lock.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ40X200-30 carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 kgf | |
The SAUJ40X200-30 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Legacy SU-family variants: SUD (double rod), SUJ (adjustable stroke) — each maps to its SAU equivalent (SUD→SAUD, SUJ→SAUJ). The current SAU line adds the SAUF valve-integrated option.
Where the Airtac SUJ Adjustable Cylinder SUJ40X200-30 Is Used
Custom Fixture Clamping
Trimming the extend stroke by up to 30 mm on-site allows operators to dial in the exact clamping position for varying part sizes without re-engineering the fixture.
Variable Length Sorting Diverts
Adjusting the extend stop on the fly accommodates different package lengths on a sorting line, ensuring the diverting motion hits the precise transfer point.
Adjustable Push-Off Mechanisms
Tuning the extend stroke to match specific container depths prevents over-travel when pushing varied bins off a roller bed, protecting the packaging.
Replacing the Airtac SUJ Adjustable Cylinder SUJ40X200-30 with the SAUJ40X200-30
To replace the discontinued SUJ40X200-30, order the direct replacement SAUJ40X200-30, which preserves the 40 mm bore, 200 mm stroke, 30 mm adjust window, 1/4" port, and FA/LB mounting. The 30 mm adjust window is ideal when you need precise field tuning of the extend stroke without machining. Because this specific SKU lacks a magnet, it cannot accept a sensor; if you need position detection, select the -S version of the SAUJ and use CMSG/DMSG/EMSG switches. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding. The external stop screw sets the end position but does not lock the load; for held loads, add an external rod lock or pilot-operated check valve.
Replacement checklist
- ✓ Same bore / stroke → SAUJ40X200-30
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S): sensor family CS1-B → CMSG
- ✓ Mounting reused (FA/FB/CA/CB/LB)
- ✓ Need a built-in valve? → SAUF
Airtac SUJ Adjustable Cylinder SUJ40X200-30 FAQ
Yes, the SUJ40X200-30 is discontinued. The direct replacement is the SAUJ40X200-30, which matches the 40 mm bore, 200 mm stroke, 30 mm adjust window, 1/4" port, and FA/LB mounting. The SAUJ also uses current CMSG/DMSG/EMSG sensors instead of the legacy CS1-B/DS1-B switches.
The external stop screw allows you to shorten the extend stroke by up to 30 mm on-site, giving a usable stroke range of 170-200 mm. The stop sets end position and is not a load lock.
